Merge tag 'media/v4.20-6' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:
 "First set of media patches contains:

   - Three new platform drivers: aspeed-video seco-sed and sun5i-csi;

   - One new sensor driver: imx214;

   - Support for Xbox DVD Movie Playback kit remote controller;

   - Removal of the legacy friio driver. The functionalities were ported
     to another driver, already merged;

   - New staging driver: Rockchip VPU;

   - Added license text or SPDX tags to all media documentation files;

   - Usual set of cleanup, fixes and enhancements"
